I just got some while washing dishes. but I had been standing up for a while before that frying some pork chops . its a tightening in the belly. but it doesn't last long for me. makes me legs kind of weak .

Well it's usually while I'm sittin down but if I get up and walk around the feelin leaves

If you switch positions and they stop, then it's Braxton hicks. I've been getting false contractions too, they're no fun

That's what it feels like.. A tightening in my lower stomach All across the bottom and it last like 30 secs

just an uncomfortable tightening of your belly really. if they're painful and consistent or get stronger, you'll want to go to the hospital. but if they're just uncomfortable and inconsistent, they're Braxton hicks
